TodZZ whom it may concern:

Be it known that I, Harms Dnrnaic'n, a citizen of the United States of America,

siding-at East- Liverpool, in the county of Columbiana and State of Ohio, have invent.- ed certain new and useful Improvements in Dia h'ragms for Printing and Decorating Irregu ar Surfaces, of'which the following is a specification, reference being had therein to t 1e accompanying drawing.

This invention relates to improvements in diaphragms for'priiiting and dec'oratin ir-- regular surfaces, as ottery ware, tile, srilierical bodies, or any at, elliptical, cylindrical,

conical, convex or concave surfaces, and the invention relates morearticularly to -the novel, efiicient and quic application-of air under pressure to that part of the dia hragrn where the pressure is most needed, or-properfect im ression of the type or configuration carrie by the diaphragm.

The invention has for its primary object to provide a stationary head and novel, means 0 fastening the diaphragm upon the same. other object of this invention is to pro- 'vide a diaphragm head with a novel air inlet, whereby the diaphragm of the head can be ex anded to enter depressions of consider;

ab e depth in vessels of pottery were or the like, thus insuring a osltive en agement of the diaphragm with a 1 parts of the surface of i the ware being decorated.

I am aware of diaphragm heads havingbeen used wherein air is admitted at the periphery of the heads, but such heads have generallyproven defective insomuch as it is impos- 'sible to force the diaphragminto de ressions in the ottery ware of considerable epth, or

to reac the bottom of a concave surface with satisfactory results. In constructing a diaphragm head in accordance with my invention, I arrange the air inlet whereby the air will impinge the central portion of the diaphragm, and force the same outwardly to insure a positive contact of the diaphragm with all portions of the de ressions m a piece of pottery ware or the lie when the same is placed on the head, or. against which the head is laced.

In admitting air be-,1

My invention simply resides in thenovel. construction of the ead'or disk'l, and the manner. of admitting air centrally of the head or disk.

, .It is obvious that the device is extremely simple in construction and can-be manufactured at a comparatively small expense.

What I claim and desire to secure by Leti ters Patent, is':-

1; In adevice of the class described, the combination with an air supply i e, ofa disk having eripheral flanges, said i ing a'centrali o enin formed therein, anjinteriorly thre'aed s eeve 'mounted in said mounted centra to receive the end of saidairrsupply pipe, a'

opening and adapted to en age .the end of. said 119e," aresilient diap ragm mounted ing the design to be upon-said disk and ca printed, a metallic ban for holding the edge of said diaphragbm, and means for securing the endsof said .and together, substantially as described. I V

2. In a diaphragm head,'the combination with an ain'supplypipe, of'a disk, .a sleeve y of said disk and adapted spider partition formed in the end 'of said s eeve,- a diaphragm. detachably' mounted sem s upon said disk and having type, and a band for holding said diaphragm upo'n said .3. In a device of the class described, the

combination with. an air suppl pi e, of a 7 diskhaving a central opening t eretough,

an interiorly threaded sleeve mounted in said 0 en-in'g and adapted to engage-the end of sai pipe, aresilient diaphragm niounte'd upon said disk and carrying the desi n to Be printed, and means for-securing't e dia-I 1 1 ipe, 'of a y oi and meansor holding said diaphragm'upon said disk. 3
